MAGNETIC DISK DEVICE AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18180463 titled 'MAGNETIC DISK DEVICE AND METHOD
Simplified Explanation
The patent application describes a magnetic disk device with a control circuit that can change the recording method for different storage regions on the disk.
- Magnetic disk device with multiple storage regions in the radial direction
- Control circuit can change recording method for each storage region individually
- Control circuit responds to commands to change recording method for specific storage regions
- Magnetic head moves to the next storage region after changing recording method for a specific region
Potential Applications
The technology described in this patent application could be applied in various data storage devices where different recording methods are needed for different regions of the storage medium.
Problems Solved
This technology solves the problem of efficiently changing recording methods for different storage regions on a magnetic disk, allowing for more flexible data storage options.
Benefits
The benefits of this technology include improved data storage efficiency, flexibility in recording methods, and potentially increased data storage capacity on magnetic disks.
Potential Commercial Applications
Potential commercial applications of this technology could include data centers, cloud storage providers, and other industries that rely on magnetic disk storage for large-scale data storage needs.
Possible Prior Art
One possible prior art for this technology could be existing magnetic disk devices that allow for changing recording methods, but perhaps not on a per-region basis as described in this patent application.
What are the specific recording methods that can be changed for each storage region on the magnetic disk device?
The specific recording methods that can be changed for each storage region on the magnetic disk device are not explicitly mentioned in the abstract. It would be helpful to know the range of recording methods that can be applied and how they differ from each other.
How does the control circuit determine when to move the magnetic head to the next storage region after changing the recording method for a specific region?
The abstract mentions that the magnetic head moves to the next storage region after changing the recording method for a specific region, but it does not detail how the control circuit determines the timing for this movement. Understanding this process could provide insights into the efficiency of the overall data storage operation.
Original Abstract Submitted
According to an embodiment, a magnetic disk device includes a magnetic disk, a magnetic head, and a control circuit. The magnetic disk has a plurality of first storage regions disposed in the radial direction. The recording method is changeable for each of the plurality of first storage regions. The control circuit operates such that, when having received a first command instructing to change the recording method of one first storage region out of a plurality of first storage regions, the control circuit changes the recording method of the one first storage region in accordance with the first command, and moves a magnetic head onto the second storage region before receiving a second command.
